ABSTRACT:
A foot operated locking brake mechanism for preventing the rotation of a caster wheel supported on an axle within a wheel fork. A pair of support members secured to the legs of the wheel fork extend radially outward of the caster wheel. The legs of a U-shaped operating member are pivotally supported on the support members radially inward of the outer circumference of the caster wheel. A brake pad support arm is pivotally mounted on the support members radially outward of the outer circumference of the caster wheel. A cam follower which is supported between the legs of the U-shaped member engages a cam surface provided on the brake pad support arm when the U-shaped member is pivoted to move the cam follower closer to the caster wheel. When the cam follower is engaged with the cam surface, a brake pad carried by the brake support arm is locked in engagement with the caster wheel tread.
